Floor heating radiates heat to the ground through underground pipes, and the floor surface radiates evenly without strong convective wind and dust. High ground temperature can kill bacteria such as attached mites, which is clean and healthy. The temperature drops evenly from bottom to top, which first warms our feet, which is in line with the health theory of "warm feet and cool top" in traditional Chinese medicine, and is very comfortable.

Air conditioning heating is to transfer heat by blowing hot air through the tuyere, which has a certain heating effect. However, strong air convection is easy to blow up ground dust. If the tuyere is not clean, it will spread viruses and bacteria, making the human body vulnerable to dust viruses. At the same time, the air conditioning temperature is uneven, and the temperature near the heat source is high. The farther away from the heat source, the worse the heating effect, and there is a heating dead angle, so the heat cannot be distributed to the whole room. Because the air outlet of the air conditioner is generally above, the indoor air is hot and cold, which is easy to cause the phenomenon of hot head and cold feet, and the comfort is not high.
